U get higher $$ if you sell it yourself.. but spend more time ..

Depends on what kind of car la..  the different is usually just $2-3K .. not worth to cost few sunday afternoon to wait for people to come see your car ..   and you dont know how is coming ..  could be scam ..  and then you also need to wait ...

Trade in la..  more easy, and just drive your old car till your new car arrive! ^_^
